The gimmick is practically invisible in performance and can provide over 100 uses before it will require a USB recharge. Highly durable and expertly manufactured, your Magma gimmick will handle years of repeated use.

Turn your fist into a furnace Magma is extremely easy to use and is everything you could wish for to inject a mutant-ability moment into your magic.

Does it "play big?" combine this with your favorite coin bend or smoke device and you'll have everything you need to start your own religion

Difficulty / Skill level required: super easy - after watching a few minutes I was able to do it right away

How much arts and crafts are involved? you "might" have to size it to fit your hands, but I didn't have to

How practical is this in the real world? (can it really be done?) this is a utility that should be used in connection with another effect. But it's just easy to use in the real world as a reel, a t.t. or something equivalent.

Overall score: let's toss out the traditional score of 1-10 and make this something that we all can appreciate and understand.
